AHA journal tones down abstract linking COVID-19 vaccines to risk of heart problems

The American Heart Association has published a corrected version of a controversial meeting abstract which claimed to show that Covid-19 vaccinations “dramatically” increased a person’s risk for serious heart problems. 

The study was the work of Stephen Gundry, a cardiac surgeon who now sells dietary supplements of questionable efficacy on his website. Gundry also sees patients at the Center for Restorative Medicine and International Heart & Lung Institute in California and offers advice on YouTube.  

Gundry submitted the abstract, titled “Mrna COVID Vaccines Dramatically Increase Endothelial Inflammatory Markers and ACS Risk as Measured by the PULS Cardiac Test: a Warning,” to the AHA’s 2021 scientific meeting, which apparently accepted it without much, if any, review. 

At the end of November, after fielding complaints about the study, the AHA issued an expression of concern for the abstract, which was riddled with spelling errors – including calling the PULS test the “PLUS” test in the first sentence, where any reader could immediately spot the mistake – and other problems:

Duke engineering prof corrects seven papers for failures to disclose startup he co-founded

Tony Jun Huang

A chemistry journal has issued corrections for seven papers after learning that one of the authors failed to list his ownership of a company with a stake in the research.  

The articles, which appeared in Lab on a Chip — a journal “at the interface between physical technological advancements and high impact applications” from the Royal Society of Chemistry — came from the lab of Tony Jun Huang, of Duke University in Durham, N.C. Huang, who holds the William Bevan Distinguished Professor of Mechanical Engineering and Materials Science at Duke, is a prominent figure in the field. According to his bio:

Authors to correct influential Imperial College COVID-19 report after learning it cited a withdrawn preprint

A March paper by researchers at Imperial College London that, in the words of the Washington Post, “helped upend U.S. and U.K. coronavirus strategies,” cited a preprint that had been withdrawn.

Retraction Watch became aware of the issue after being contacted by a PubPeer commenter who had noted the withdrawal earlier this month. Following questions from Retraction Watch this weekend, the authors said they plan to submit a correction.

In March, the New York Times wrote:

An awkward correction later, these researchers have a warning for would-be authors

Mitchell Knutson

Mitchell Knutson learned to take a journal’s policies seriously the hard way.

Early in 2017, Knutson, a professor at the University of Florida in Gainesville who studies iron metabolism, had findings he and his team were excited about publishing in the Proceedings of the National Academy of Sciences (PNAS). So they submitted a manuscript on January 30. Continue reading An awkward correction later, these researchers have a warning for would-be authors

Caught Our Notice: A paper mistakenly ID’d a patient. Its retraction notice did, too. (Oops!)

What Caught Our Attention: Last year, a journal retracted a paper about a child who developed a rare complication related to the inherited disorder Gaucher Disease, after realizing it had inadvertently identified the child. It wasn’t an immediately obvious mistake — the authors listed the drugs the patient was taking, and in the case of one drug, there was only one child in the world taking it. For anyone in the know, that would make the child’s identity clear.

So retracting the paper makes sense — but publishing a retraction notice that spells out the issue in detail, including the name of the drug and the fact the patient was the only pediatric recipient, did not. So last month, the Journal of Pediatric Hematology/Oncology corrected the retraction notice, removing the name of the drug. (Phew.)

Caught Our Notice: Climate change leads to more…neurosurgery for polar bears?

Title: Internet Blogs, Polar Bears, and Climate-Change Denial by Proxy

What Caught Our Attention: There’s a lot going on here, so bear with us. (Ba-dum-bum.)

First, there was the paper itself, co-authored by, among others, Michael Mann and Stephan Lewandowsky. Both names may be familiar to Retraction Watch readers. Mann is a prominent climate scientist who has sued the National Review for defamation. A study by Lewandowsky and colleagues of “the role of conspiracist ideation in climate denial” was the subject of several Retraction Watch posts when it was retracted and then republished in a different form. And the conclusion of the new paper, in Bioscience, seemed likely to draw the ire of many who objected to the earlier work: Continue reading Caught Our Notice: Climate change leads to more…neurosurgery for polar bears?

Caught Our Notice: Yes, a 20-year-old article is wrong — but it won’t be corrected online

Title: AMPA receptor-mediated regulation of a Gi-protein in cortical neurons

What Caught Our Attention:  Usually, when journals publish corrections to articles, they also correct the original article, except when the original is unavailable online.  When Nature noticed that some figure panels in a 20-year-old paper were duplicated, it flagged the issue for readers — but didn’t correct the online version of the original paper. According to the notice, the duplications don’t disturb the conclusion illustrated by the figure, the original data couldn’t be found, and the last two authors had retired. We contacted a spokesperson at Nature, who told us “the information at the start of the paper clearly links to the corrigendum.”   Continue reading Caught Our Notice: Yes, a 20-year-old article is wrong — but it won’t be corrected online

Caught Our Notice: “The first author cut the thermoprinter paper printout into pieces and reassembled them”

Title: A mitochondrial ferredoxin is essential for biogenesis of cellular iron-sulfur proteins

What Caught Our Attention: Here’s a cut-and-paste issue that gave us pause. The authors of an 18-year-old paper in PNAS corrected it after realizing some bands in a figure were duplicated (an issue raised on PubPeer one year ago). It turns out, the first author had cut the paper into pieces and reassembled them to present the blots in the “desired order,” and some had become duplicated by mistake. The overall results were unaffected, so the journal swapped the image with a corrected version. Continue reading Caught Our Notice: “The first author cut the thermoprinter paper printout into pieces and reassembled them”

Caught Our Notice: Voinnet co-author issues another correction

Title: AtsPLA2-α nuclear relocalization by the Arabidopsis transcription factor AtMYB30 leads to repression of the plant defense response

What Caught Our Attention:  A previous collaborator with high-profile plant biologist Olivier Voinnet (who now has eight retractions) has issued an interesting correction to a 2010 PNAS paper. Susana Rivas is last author on the paper, the correction for which notes some images were duplicated, and others were “cropped and/or stretched to match the other blots.” Rivas is currently a group leader at The Laboratory of Plant-Microbe Interactions (LIPM), “a combined INRA-CNRS Research Unit.” Continue reading Caught Our Notice: Voinnet co-author issues another correction

Caught Our Notice: Big journal, big correction

Title: Tranexamic Acid in Patients Undergoing Coronary-Artery Surgery

What Caught Our Attention: When the New England Journal of Medicine (NEJM) publishes a correction that is more than a misspelling of a name, we take a look. When NEJM publishes a 500-word correction to the data in a highly cited article, we take notice. This study tested the effects of a drug to prevent blood loss in patients undergoing heart surgery; it’s been the subject of correspondence between the authors and outside experts. The correction involved tweaks — lots of tweaks — to the text and tables, which did not change the outcomes.   Continue reading Caught Our Notice: Big journal, big correction
